For particular forms of a general volatility function, analytical solutions of the Black-Scholes PDE can be found. However, it tends to be the case that the more 'realistic' the volatility function is, for instance with a volatility smile, analytical solutions become difficult to obtain. In this...

Collateral is one of the most important and widespread credit risk mitigation techniques used by practitioners. This paper studies the effect of mark-to-market (MTM) timing in collateral agreements on the contingent credit risk exposure. We measure contingent credit risk exposure using Potential...

This paper presents a forecast tracker that can help bridge the wide gap between formal econometric forecasting methods and the common practice of judgmental forecasting. Traditionally, out-of-sample forecast errors have been widely used to improve the accuracy of econometric models, but track...

This paper provides a formal definition of emergence, operative in multi-agent framework and which make sense from both a cognitive and an economics point of view. The first part discuses the ontological and epistemic dimension of emergence and provides a complementary set of definitions....

Total factor productivity (TFP) computed as Solow-residuals could be subject to input-substitution bias for two reasons. First, the Cobb-Douglas (CD) production function restricts all input substitutions to one. Second, observed inputs generally differ from optimal inputs, so that inputs...

Computing equilibria in dynamic economies is still quite challenging even though the noticeable increase in computing power, storage capacity and new approaches in the literature on computational economics. The solvability of many economic models suffers from the curse of dimensionality, which...

This paper characterizes the optimal inflation buffer consistent with a zero lower bound on nominal interest rates in a New Keynesian sticky-price model. It is shown that a purely forward-looking version of the model that abstracts from inflation inertia would significantly underestimate the...

The paper implements reverse shooting to solve for global nonlinear saddle path for optimal control problems with two state variables. It shows how to do reverse shooting. This will reduce entry barriers for researchers for whom this technique may be useful. For this purpose, user-friendly...

We study individual evolutionary learning in the setup developed by Deissenberg and Gonzalez (2002). They study a version of the Kydland-Prescott model in which in each time period monetary authority optimizes weighted payoff function (with selfishness parameter as a weight on its own and...

The nature of computing is changing and it poses both challenges and opportunities for economists. Instead of increasing clock speed, future microprocessors will have "multi-cores" with separate execution units. "Threads" or other multi-processing techniques that are rarely used today are...
